continuous slot screen

 We are a manufacturer of continuous slot wedgewire well screen in china. The wedgewire products are manufactured by rolling a V-Shape wire around an internalframework of longitudinal bars. The external V-Shape wire can have either a sharp end, in what is known as Vee-Wire Sharp, or it can have a round end in what is known as a Vee-Wire Wear. Depending on the type of wire used and the slot opening, the open area of a wedgewire screen can vary between 10% and 70% of the total area (see graph). The average opening area of a water well screen varies from 35% to 45% compared with 5% to 15% on average of a other screens (e.g. perforated or bridge screen). In the case of support grids, the filtering area can be up to a 70% of total area, depending on the material used and the slot.The continuos slot water screen has several advantages compared to other screens such as bridge slot screen or perforated screen A larger opening (filtering) area of a wedgewire screen leads to superior performance of a water well compared against the installation of other types of screens. Moreover a wedgewire filter for water well are self-cleaning (go-no go), thus, prevents losses due to friction as well as losses associated with pumping sand. Also, a continuous slot wedgewire water well screen eliminate the problems associated with fine sands, thus, increasing the life of the pumping equipment.Please tell us your demand and then we design ,manufacture for you.Yours faithfully bob.
